Carbon in the Arctic Vulnerability Experiment (CARVE) - Overview Key Science Questions: What are the sensitivities of the Alaskan Arctic carbon cycle and ecosystems to climate change? How does interannual variability in surface controls (e.g., soil moisture) affect landscape-scale atmospheric concentrations and surface-atmosphere fluxes of CO2 and CH4 in the Alaskan Arctic? What are the impacts of fire and thawing permafrost on the Alaskan Arctic carbon cycle and ecosystems?

Conclusions The use of SciDB is found to be well suited for the processing of satellite data for CARVE Successful implementation of an operational freeze/thaw product at near-real-time latency Thermal infrared and passive microwave instruments can be used to observe freeze thaw processes This will enable the use of high resolution monitoring of freeze/thaw processes using FLIR imager Future Work Combine remote sensing products with aircraft and in-situ carbon measurements and surface process modelling Use remote sensing measurements for the spatiotemporal distribution of carbon cycling of CO 2 and CH 4
